Abstract

The embodiment of the application discloses a method and device for determining the audio frequency of keys, and the method and device is applied to a key detection platform, wherein the key detectionplatform comprises an antenna array, the antenna array comprises a plurality of antenna units, and each antenna unit sends and receives signals based on an inductive coupling mode. The method comprises the following steps that a first detection signal is sent based on antenna units in the antenna array, the first detection signal is used for identifying keys pressed in a keyboard, and the keys comprise electronic tags which are used for receiving the first detection signal sent by the antenna units of the antenna array and feeding back response signals; and response signals fed back by the electronic tags of each key in the plurality of keys of the keyboard are received based on the antenna array, and key tones corresponding to each key is determined according to the response signals fedback by the electronic tags of the keys. By adopting the embodiment of the application, the key tone determining is low in cost, high in realizability and wide in application range.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for determining the audio frequency of a key. Background technique [0002] In a traditional electronic keyboard or piano, each key is a small switch in the circuit. When a key is pressed, its corresponding small switch is closed, so that the virtual key pressed can be determined and the corresponding virtual key is output. Touch-tone. However, this kind of electronic organ or piano is expensive, and cannot recognize the sheet music, so the applicability is not high. Contents of the invention [0003] Embodiments of the present application provide a method and device for determining the audio frequency of a piano key. The cost of determining the key tone can be reduced, the implementation degree is high, and the application range is wide. [0004] In the first aspect, an embodiment of the present application provides a method for determining t...
